Cells are often ground up with abrasive to get to their internal enzymes/molecules, followed by removal of the abrasives. Here a
re two situations and two outcomes. What is the correct interpretation of the results? In situation #1, radioactive amino acids are mixed with ground-up cell material. Radioactive proteins are produced. In situation #2, radioactive amino acids AND the enzyme RNAse (an enzyme that degrades RNA) are mixed with ground-up cell material. No radioactive proteins are produced.Answers The mRNA from the cell can be used to make proteins with the radioactive amino acids in the first situation. In the second situation, the mRNA is destroyed by the RNAse before it can be translated into protein containing the radioactive amino acids.The DNA from the cell can be translated into protein using the radioactive amino acids in the first situation. The RNAse in the second situation degrades the ribosomal RNA (rRNA), preventing ribosomes from forming and making proteins with the radioactive amino acids.The radioactivity in the amino acids corrupts the tRNA molecules, leading to no protein production in the second scenario.The results cannot be interpreted-there isn't enough information given in the question.
The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.
The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.
The neuroendocrine system is made up of the cell in the body that ‘sit’ between the nervous system and the endocrine system. These cells are like the pituitary gland, islets cells of the pancreas, thyroids, and etcetera. They receive nerve impulses from nerves connected to them. The impulse then triggers them to release respective hormones into the blood.
In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest.
So, if the birthrate and the death rate are the same, that means that for every person that gets born, one person dies: so the number of people would stay constant. This means that the growth rate is actually 0%.
